The NAT rule destination zone should be set to Outside because that is the zone where the post-NAT IP address of the server (192.168.10.10) belongs. The destination zone of a NAT rule is the zone where the translated IP address resides. Option A is incorrect because None is not a valid zone for a NAT rule. Option C is incorrect because DMZ is the zone where the pre-NAT IP address of the server (153.6 12.10) belongs, not the post-NAT IP address. Option D is incorrect because Inside is not a zone that is configured on the firewall.
An administrator is troubleshooting why video traffic is not being properly classified.
If this traffic does not match any QoS classes, what default class is assigned?

Suggested Answer: D Vote an answer

Explanation
The default class that is assigned to traffic that does not match any QoS classes is class 4. Class 4 is the default class for any session not matched to a QoS policy. QoS policy, like security policy, is processed top to bottom and the first policy match will be applied. If no policy match is found, the traffic is assigned to class 412.
Option A is incorrect because class 1 is not the default class for unmatched traffic. Class 1 is a user-defined class that can be used to assign traffic based on QoS policy criteria. Option B is incorrect because class 2 is not the default class for unmatched traffic. Class 2 is a user-defined class that can be used to assign traffic based on QoS policy criteria. Option C is incorrect because class 3 is not the default class for unmatched traffic. Class 3 is a user-defined class that can be used to assign traffic based on QoS policy criteria3.
